Nineties pop star Richard Marx and his wife Daisy Fuentes found themselves caught in the middle of a terrifying mid-air incident when an unruly passenger had to be subdued by passengers and crew, including Marx himself.

The couple took to social media to share photos of their terrifying experience while traveling from Vietnam to South Korea on Korean Air. A passenger became violent and started attacking the flight attendants and other passengers. Marx apparently jumped in to try and diffuse the situation, which staff struggled to handle because of the unruly passenger's outbursts.

"On our flight from Hanoi to Seoul a guy sitting in the next row from us got crazy &started attacking the flight attendants &passengers. When he started pushing the female staff and pulling them by the hair @therichardmarx was the first to help subdue him," Fuentes wrote in the caption.

"This went on for FOUR hrs. I feel horrible for the abuse the staff had to endure but no one was prepared for this. They never fully got control of him. They didn't know how to use the taser &they didn't know how to secure the rope around him (he got loose from their rope restraints 3 times)."

The grid of photos shows a flight attendant pointing a Taser gun at the passenger, as well as Marx holding him down. In another photo Marx holds white rope, presumably to tie up the passenger. Fuentes noted that she would post video of the tumultuous flight after she and her husband reached their destination.
